pembrolizumab and axitinib as neoadjuvant therapy for locally advanced non-metastatic clear cell renal cell carcinoma

Conditions: Renal Cell Carcinoma; Clear Cell Renal Cell Carcinoma

Summary: this is a single-arm phase ii clinical trial to evaluate the initial efficacy and safety of pembrolizumab combined with axitinib as neoadjuvant therapy for locally advanced non-metastatic clear cell renal cell carcinoma.

this study is design to prospectively investigate the safety and efficacy of pembrolizumab combined with axitinib in downsizing tumors in patients with nonmetastatic biopsy-proven clear cell renal cell carcinoma. this is a single-institution, single-arm phase 2 clinical trial. patients will receive axitinib 5 mg bid on days 1-21 combined with pembrolizumab intravenously (iv) over 30 minutes on day 1. treatments repeat every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity.patients then will receive partial or radical nephrectomy after neoadjuvant therapy.
